Question
Like the title states, I need to make my program wait until my NSOpenPanel
closes. I have the panel open in windowControllerWillLoadNib
so that it happens before my document window opens. But what happens is that, it just loads both windows without waiting for the panel to close. How can I make it wait until the open panel is closed and completely finished?
Solution
use runModal method.
Code example:
int result;
NSOpenPanel *oPanel = [NSOpenPanel openPanel];
result = [oPanel runModalForDirectory:NSHomeDirectory() file:nil types:nil];
if (result == NSOKButton) {
//your code
}
OTHER TIPS
Set up your open panel and then you can do something like this:
if ([openPanel runModal]==NSFileHandlingPanelOKButton) {
// get the urls
NSArray *fileURLs = [openPanel URLs];
} else {
// cancel button was clicked
}
runModal stops the execution of your program until the panel closes.
